Callum Kennedy and Sean Morrison have both signed contract extensions with Swindon that will see them remain at the League One club until the summer of 2010.
Centre-back Morrison, 18, initially broke into Swindon's first-team towards the end of last season and has gone on to make 16 appearances this term, scoring one goal in the 2-0 home victory against Oldham.
Fellow youngster Kennedy also made his first start for the club last year before finally breaking through during pre-season back in the summer.
But the full-back had to wait until December before getting his first taste of the action in the 1-1 draw against Carlisle.
The young duo have attracted a lot of attention from rival clubs so far in the early stages of their careers and boss Danny Wilson will be delighted to have tied them down at the County Ground.
